how to determine the lubricant temperature in gear meshing ?
 

In my job I have to determine the field of temperature between the tooth of an helical gear along his width. The temperature is due to the compression of the fluid, and at the point where the oil is ejected we have measured a decreasing temperature because of the expansion. As I'm not a spécialistis in thermodynamic I have some difficulties. Can you help me to find a way to solve my problem ?

Thanks
